Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam adhesive production technology, and specifically to a foam adhesive production system. Background Technology
[0002] Expanded polyurethane foam, as the name suggests, is an adhesive with foaming and bonding properties. It is mainly used for filling, sealing, and bonding gaps in building doors and windows, expansion joints in structural components, and holes. It is a polyurethane elastic sealing foam material that cures by moisture.
[0003] The preparation process of expanded polyurethane foam involves directly adding various raw materials to a reaction vessel for stirring and reaction. However, due to the viscosity of the resin and other raw materials, stirring is difficult and inefficient, resulting in low production efficiency of expanded polyurethane foam.
[0004] Therefore, it is necessary to propose a foam production system that can effectively reduce the viscosity of resin raw materials and improve mixing efficiency, thereby enabling faster production of foam. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a foaming adhesive production system that can effectively reduce the viscosity of resin raw materials, improve stirring efficiency, and thus produce foaming adhesive faster.
[0006] The purpose of this utility model is achieved through the following technical solution: a foamed adhesive production system, including a reaction stirring vessel and a pre-stirring component, wherein a connecting pipe is provided between the pre-stirring component and the reaction stirring vessel, a conveying pump is provided on the connecting pipe, a methane feed pipe is connected to the reaction stirring vessel, and a discharge pipe is connected to the lower end of the reaction stirring vessel.
[0007] It also includes a frame, on which the reaction stirring vessel is embedded.
[0008] The reaction vessel includes a stirring section, and a cooling layer that can be filled with water is provided on the outside of the stirring section. The reaction vessel is provided with an inlet pipe and an outlet pipe that are connected to the cooling layer.
[0009] The horizontal height of the inlet pipe is lower than that of the outlet pipe.
[0010] The pre-mixing component is a mixing tank located on the ground, with an opening on the upper side of the mixing tank.
[0011] It also includes a dust extraction device located directly above the mixing tank, which is connected to an exhaust pipe.
[0012] A hollow lifting assembly with both ends connected to the dust extraction component and the exhaust pipe is provided between the dust extraction component and the exhaust pipe.
[0013] The dust extraction component has base blocks at both ends, and a sliding rod located on the ground slides through the base blocks. The hollow lifting assembly includes a hollow mother rod and a hollow son rod that slide together. A hollow gear is rotatably installed inside the hollow mother rod. The hollow gear is threadedly mounted on the hollow son rod. A bevel gear meshes with one side of the hollow gear. The bevel gear is connected to a first sprocket. The first sprocket is connected to a second sprocket via a chain drive. A motor is installed on the outer wall of the exhaust pipe. A connecting rod is installed at the output end of the motor. The connecting rod rotatably passes through the hollow mother rod and connects to the second sprocket.
[0014] The beneficial effects of this utility model are: by setting up a reaction stirring tank and a pre-stirring component, and by setting a methane feed pipe on the reaction stirring tank, the raw materials such as resin are pre-stirred first, and then fed into the reaction stirring tank for complete stirring. Methane effectively reduces the viscosity of the resin, thereby improving the stirring efficiency. Furthermore, the pre-stirring and complete stirring can be more thorough, thereby further improving the production efficiency and quality of foamed adhesive. Attached Figure Description
